The World Cup of Gems - United States

I just read that Tourmaline was the first gemstone mined in the United States "by miners other than prehistoric man or Native Americans." I thought this was an interesting way to put things. The year was 1822 and the place was Mount Mica, ME.

Tourmaline is also found, within the U.S., in California - and there in large quantities.

It is very popular because it can be found in almost any color. Green, Shades of red, blue green to light blue, and colorless.

Tourmalines have many scientific uses because it has a property known as piezoelectricity. An electrical charge can be induced in some tourmaline crystals simply by applying pressure to the crystal in the direction of the vertical crystal axis.

On the metaphysical level tourmaline is supposed to enhance a person's understanding and increase self-confidence. They are also supposed to neutralize negative energies and are thus useful in relaxing the body and mind. They are used in the treatment of infectious diseases, anxiety, blood poisoning, arthritis, and heart disease.
